产品介绍

生物活性

Recombinant Mouse Interleukin-4 is a pleiotropic cytokine regulates diverse T and B cell responses including cell proliferation, survival, and gene expression. It is produced by mast cells, activated T cells and bone marrow stromal cells. IL-4 regulates the differentiation of native CD4+ T cells (Th0 cells) into helper Th2 cells, and regulates the immunoglobulin class switching to the IgG1 and IgE isotypes. IL-4 also plays a major role in inflammation response and wound repair via activation of macrophage into M2 cells.

The ED50 as determined by the dose-dependant prolifiration of Murine HT-2 cells is less then 2 ng/ml, corresponding to a Specific Activity of > 5 × 105IU/mg.

Source: Escherichia coli.

Molecular Weight: Approximately 13.5 kDa, a single non-glycosylated polypeptide chain containing 121 amino acids.

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)

小鼠大鼠豚鼠仓鼠
重量 (kg)0.020.151.80.40.0810
体表面积 (m2)0.0070.0250.150.050.020.5
Km系数36128520
动物 A (mg/kg) = 动物 B (mg/kg) × 动物 B的Km系数
动物 A的Km系数

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
